- function [ret,x0,str,ts,xts]=sim12x9b(t,x,u,flag);
- %SIM12X9B is the M-file description of the SIMULINK system named SIM12X9B.
- % The block-diagram can be displayed by typing: SIM12X9B.
- %
- % SYS=SIM12X9B(T,X,U,FLAG) returns depending on FLAG certain
- % system values given time point, T, current state vector, X,
- % and input vector, U.
- % FLAG is used to indicate the type of output to be returned in SYS.
- %
- % Setting FLAG=1 causes SIM12X9B to return state derivatives, FLAG=2
- % discrete states, FLAG=3 system outputs and FLAG=4 next sample
- % time. For more information and other options see SFUNC.
- %
- % Calling SIM12X9B with a FLAG of zero:
- % [SIZES]=SIM12X9B([],[],[],0), returns a vector, SIZES, which
- % contains the sizes of the state vector and other parameters.
- % SIZES(1) number of states
- % SIZES(2) number of discrete states
- % SIZES(3) number of outputs
- % SIZES(4) number of inputs
- % SIZES(5) number of roots (currently unsupported)
- % SIZES(6) direct feedthrough flag
- % SIZES(7) number of sample times
- %
- % For the definition of other parameters in SIZES, see SFUNC.
- % See also, TRIM, LINMOD, LINSIM, EULER, RK23, RK45, ADAMS, GEAR.
- % Note: This M-file is only used for saving graphical information;
- % after the model is loaded into memory an internal model
- % representation is used.
- % the system will take on the name of this mfile:
